It can get wet, but not actually go under water. Fantastic sound. You can connect and “pair” several of these speakers. I am using one (1) in a relatively small house. I move it from bedroom to living room to kitchen (when I am listening to music). Comes with an app, called JBL connect which allows you to control several of these units. It has an absolutely amazing battery. It charges very rapidly (via USB) and runs for some 10-12 hours, depending on your usage. It also has a voice option (for handsfree calling using your phone).
